To rtZZ whom it TIL/Ll] concern:

Be it known that i, EDWARD L, Arman, a citizen of the United States, anda resident of East Orange, in the county of Essex and State of NewJersey, have invented certain new and useful improvements inPhonographs. of which the following is a descrip- My invention relatestophonographs, and

more particularly to phonographs of the type shown in UnitedStates-Patent No.

and l-libbard.

My invention has for its object the pro- 772385, granted October18,1.904, to -VV'eber' vision of improved means for raising and,

loweringthe arm which carries the reproducer or recorder and for causingthe same tobe stepped in a rearward direction whenever desired, saidmeans being adapted to prevent accidental displacement of the recorderor reproducer with respect to the record-surface, especially when theinstrument is being used by beginners or those not particularly skilfulin its use.

Myinvention also comprises certain other details of construction, which.will be hereinafter fully set forth.

Referring to the accompanying drawings, Figure 1 is an end View of aphonograph embodying my invention, the recorder or repro ducer framebeing elevated so that the feednut is disengaged from the feed-screw.Fig. 2 is a broken plan view of the same: Fig. 3

is a view similar to Fig. 1, certain of the parts being removed for thesake of sunplicityand clearness and shows the positions assumed by theparts when the recorder or reproducer carrier-arm is elevated and 1s lieings stepped in a rearward direction. Fig.4

is a similar view showing the parts when the recorder or-reproduccr isin operative posi tion with respect to the rotating record or l lank.-Fig. 5 is a detail plan view of the mechanism for stepping thecarrier-armrearward.

The phonograph shown com 'iriscs a bod y 1 and back rod 2, which extendstransversely thereof and upon which the sleeve 3 is mounted to slide inthe usual manner, said sleeve carrying the usual feed-nut spring t andfeed nut 5. Parallel with the rod 2 is the feed-screw 6, which operatesin the usual manner to impart forward movement to the into contact withthe record-surface.

sleeve Parallel with the rod 2' is a front guide-rod 7, which isadapted. to support the forward end of the carrier-arm 8, extendingforward from and preierably integral with the sleeve 3. This arm isprovided with a depending projection 9, which rests upon the rod-7 whenthe feed-nut is in engagement with. the feed-screw, as shown in Fig.4-.-- An auxiliary arm 10 is pivoted on a pin 11, can ried by the arm 8.

screw' '13, carried by the said arm, said spectacle-frame being adaptedto turn on its is raised by lifting uponthc finger-piece 26,

so that the auxiliary arm 10 'turns onthe pivot-pm 11.

In order that the recorder and reproducer may operate upon blanks orrecords which vary gradually in diameter, it is desirable" The arm 10carrier af spectacle-trame .12, which is pivoted ona that recorders andreproducers of the Floatingweight type he used in which the weights havea large range of movement: In using such instruments it is desirable toprovide 7 means for sustaining the weight belonging to the rcproducerwhen therecorder is in operative position, and vice versa, becauseespe-. cially when operating upon a large blank the wveiglit belongingto the inactive instrument would be likely to occupy, a position.suflicientlylow as to bring the stylus thereof In order to preventthis, a plate 14 is secured-to the forward end of the arm 8 by screws1.5, its position being such that when the spec: tacle-frame is inposition i or the recorder to operate upon the blank, as in Fig. 1, theweight 16 ol. the reproducer will rest upon one end of the said plate14, and, vice versa,

wl'ien the reproduccr is in. operative position 7 the weight 17 of therecorderwilltrest upon the other end of the plate 14. v

The means for elevating the (3&IIilil'l11 8 comprises a lift-lever 18 ofpeculiar form. This lever is pivoted. on a screw 18*, secured to the arm8, so as to turn on a horizontal IS turned on its for the lever 18 inboth directions, as shown concave surface formed upon the rear edge ina'rearward direction.

plished by the movement of the lever 18,

. which is provided with a cam-surface 20, so

'arm on the pin 1.1 is limited there would be a along the rod 2',

to move in an are described about the point axis parallelto the rod 7.The finger-piece 19 extends outward from the body of the lever 18, sothat it may be readily manipw. lated by the operator for'moving thelever,

situated as to be brought into operative/contact with the supporting-rod7 as the'lever pivot, thus effecting the elevation of the arm 8 from theposition of Fig. ft to that of Fig. 1. The body of the lever 18 is cutaway, as shown at 21, to receive the end of the pin.11, which operatesas a'stop in Figs. l and 4. {that spring .22'is secured at one .end tothe arm 8 by a stud 23 and is arra. god to press against. the arm 17 andhold it in either of its extreme positions. In one position the springpresses against a of the lever 18, as shown in Fig. 4, and in the. otherextreme osition the spring presses u on the end of the tooth 2.4, as inFig. 3. p e lever 18 also carries a hook 25, the end. of which.isimmediately below the rod 7 when the arm'8 is depressed and the feed-nutinungagement with the feed-screw. In this position the hook 2-5.prevents the arm 8 from eing raised. This is desirable, because inshifting I the spectacle-frame .the operator seizes the finger-piece 26so as to-raise the arm 10, and as the pivotal movement of said tendencto move the arm 8, so as to release the fee enut 5 from the feed-screw,and it would then be possible for the arm 8 to slide. thus displacingthe recorder or reproducer with respect to the record-surface. With thestructure shown, however, the spectacle-frame ma. be readily shifted,and it is impossible in t is Wayto move the arm 8 either vertically orlaterally. i... i The lever 18is provided with a boss or projection 27,in which a screw 28 ismounted. Pivoted'upon' said screw is a pawl 28,which is normally held in the position shown in Fig. 4 by a coil-spring29, secured at one end to the screw 28 or boss 27 and at the other endto a small pin 30, carried by the pawl. The rear surface of the rod 7 isprovided with teeth forming a rack 31, the said teeth being adapted tobe engaged by the pawl 28 when it is desired to step the arm 8 a shortdistance This is accomwhich first effects the elevation of the arm 8 bythe cooperation of the cam-surface 20 and rod 7, so as to separate thefeed-nut and the and a further movement brings one of the teeth of therack 31 as shown in Figs 3 and 5. A further movement of the lever 18causes the pawl to move the arm 8 rearward, since the free end or pointof the pawl is held by the rack, causing. the pin 28 of the pawl as acenter until the said point leaves therack 31, as shown in Fig-2, thelever 18 being then ii -its extreme position. YVhen the 'partslassiihlethis relation, the sleeve 3 can be movedifreeflyiu on the rod 2 and therecorder or reproducer brought into upon the "record, which is thepurpose 'for.

which the reproducer is usually stepped rearward. Of course a veryslight movement of the lever 18 from the position of Fig. .4 will raisethe feed-nut from the feed-screw and enable the arm. 8 to be movedlaterally, if desired.
